Book of Adam and Eve Chapter 26

4 Then Satan, the hater of all good, said to Adam, "O Adam, I am an angel of the great God; and, behold the hosts that surround me. 5 God has sent us to take you and bring you to the border of the garden northwards; to the shore of the clear sea, and bathe you and Eve in it, and raise you to your former gladness, that you return again to the garden."

"Behold, we go to the sea of water," and they began to go. 9 And Adam and Eve followed them at some little distance. 10 But when they came to the mountain to the north of the garden, a very high mountain, without any steps to the top of it, the Devil drew near to Adam and Eve, and made them go up to the top in reality, and not in a vision; wishing, as he did, to throw them down and kill them, and to wipe off their name from the earth; so that this earth should remain to him and his hosts alone.
